Frequently Asked Questions
How many steering parts fit the 2021 BMW I3S?

Do steering parts differ between 2021 BMW I3S engines?
No. On this page every steering part fits both the 647cc L2 ELECTRIC and the 647cc L2 ELECTRIC/GAS. You do not need to pick an engine to choose the right row — use the notes for position and trim.
What are the signs of steering problems on a 2021 BMW I3S?
Common symptoms include play or looseness on center, a whine when turning, fluid weeping from rack boots, or uneven tire wear on the front axle. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the inner and outer tie-rod ends together on higher-mileage vehicles, then get an alignment.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 BMW I3S was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2021 BMW I3S?
Every part on this page already fits both the 647cc L2 ELECTRIC and the 647cc L2 ELECTRIC/GAS. Then flush old power-steering fluid when replacing a pump or rack — grit in the old fluid is the number-one cause of repeat failure. The notes column carries position and trim qualifiers where they apply.
